OCHS stood for Oshawa Catholic High School. It is now known as Paul Dwyer High School. It is still located at 700 Stevenson Road North in Oshawa, Ontario, Canada.
These images are from my photography archives, and they are intended as a blast from the past. I have just digitized these images from dusty negatives that have not seen the light in a pile of years.
In addition, other archive photos have been added from contributions by graduates and teachers of the high school.
